Question

Alan is building a fence around his fish pond. The fish pond is in the shape of a rectangle with a length of 60 feet and a width of 40 feet. It took alan 16 hours to complete the fencing. What is the unit rate at which alan put fence around his fish pond

Answer 1

12.50 ft per hour

Explanation:

Given that:

Fish pond has a rectangular shape.

Length of fish pond = 60 feet

Width of fish pond = 40 feet

Total time to complete the fencing = 16 hours

To find:

Unit rate of putting the fencing around the fish pond.

Solution:

First of all, we need to find the total fencing to be put around the fish pond.

Total fencing is nothing but the perimeter of the fish pond which is of rectangular shape.

Formula for perimeter of rectangular shape is given as:

`Perimeter = 2* (Length + Width)`

`Perimeter = 2* (60+40)\\\Rightarrow Perimeter = 200\ ft`

Unit rate is the perimeter divided by total time taken to put the fencing around.

Therefore,

Unit rate =
`(200)/(16) = \bold{12.5}` feet per hour

So, the answer is 12.5 feet per hour.
